Article Reference Late Cretaceous amphibians and lacertilians from Pui (Hateg Basin, Romania)
In 2000 and 2001, a joint team from Universitatea Babeş-Bolyai (Cluj-Napoca, Romania) and the Royal Belgian Institute of Natural Sciences (Brussels, Belgium) screen-washed 2500 kg of sediments from a new large lens found in the south of the Pui village along the Bărbat river. The sediments are attributed to the Maastrichtian Sânpetru Formation that yielded one of the richest and most diversified Late Cretaceous continental faunas in Europe. The red colored silty layer found at Pui, probably deposited in a northerly flowing braided river system under a warm and humid climate with seasonal fluctuations. Numerous fragments of lacertilian and amphibian microfossils were found in this site. The amphibians are represented by a Discoglossidae ind. and a Lissamphibia (Albanerpeton cf. inexpectatum). It suggests that the genus Albanerpeton came into Europe during the Late Cretaceous, instead of the Tertiary as previously thought. The lacertilians are represented by a Squamata ind., a new Teiidae (Paraglyphanodon nov. sp.) and two Paramacellodidae (Becklesius nov. sp. and aff. hoffstetteri). The stratigraphical range of the latter family is thus extended for a 70 Ma period, as this genus was previously described from Kimmeridgian deposits. The presence of Albanerpeton and Paraglyphanodon at Pui indicates a North American influence on the East European amphibian and lacertilian faunas by Maastrichtian times.

Article Reference Parataxonomic classification of eggshells from Pui in the Hateg Basin (Romania)
Examination of forty egg fragments collected from the site of Pui (Hateg Basin) has revealed a greater ootaxonomic diversity that known from complete eggs or clutches found in the other Upper Cretaceous localities from Romania (Grigorescu 1993, Grigorescu et al. 1994; Codrea et al in press). The eggshells obtained by screen-washing, were associated with a diversified microvertebrate remains (including dinosaurs, squamates, mammals…). The egg material correspond to several parataxonomic units (Mikhaïlov et al. 1996) and is referred to 5 morphotypes (discretispherulitic, prolatospherulitic, prismatic, ratite and geckonoid). The study of these ootypes provids us paleogeographical data and clues about the diversity of egg layers in the Campano-Maastrichtian from Romania

Article Reference Dinosaur egg nests, mammals and other vertebrates from a new Maatsrichtian site of the Hateg Basin (Romania)
The Toteşti-baraj site is located in the central part of the Haţeg Basin, in the northwestern part of the South Carpathians. According to the geological map of the area, the outcropping sediments belong to the Maastrichtian Sânpetru Formation. However, the general appearance in the field of the studied sediments is rather different from the sediments of the type locality of the Sânpetru Formation. The facies distribution observed at Toteşti-baraj indicates a fluvial palaeoenvironment with sandy channel infills and mainly black silty and clayey overbank deposits. At the end of spring 2001, the first Belgo-Romanian excavation campaign discovered in this locality more than forty eggs organised in 11 nests. These eggs may be referred to as the oofamily Megaloolithidae and closely resemble the eggs previously described in the Haţeg Basin and the French oospecies Megaloolithus siruguei. The locality was probably frequented as a nesting site during a large time span, as dinosaur nests have been found at different stratigraphic levels. Screen-washing of 1500 kilograms of sediments collected around the nests provided a particularly diversified microvertebrate fauna. Amphibians are represented by Albanerpetontidae and discoglossid Anura. Two types of sciencomorph lepidosaurians co-existed in this locality. Dinosaur teeth are particularly diversified in the sample collected at Totesti-Barraj. Besides hadrosauroid and nodosaurid ornithischians, at least five different kinds of isolated theropod teeth may be distinguished. But the most remarkable collected micro-remains are mammal teeth, representing at present the richest multituberculate collection from the Upper Cretaceous of Europe. The presence of at least two taxa of the family Kogaionidae (Multituberculata) is attested by fourteen complete teeth and several tooth fragments of mammals. Micropalaeontological analysis and study of vertebrates are in process in order to determine more precisely the age, the faunal content and the palaeoenvironment of the Totesti-Baraj locality.
